persistence to our fundamental research principles: a) Scientific Excellence with advanced and innovative technology concepts, b) Research with significant Impact to society and economy, c) State-of-the-art organisation for highly efficient Implementation, d) Systematic international Cooperations.
Great thanks to the highly dedicated NTUA Road Safety Research Team and
to all our European and worldwide partners. And the exciting journey
towards scientific excellence continues …  | | | |
| Latest Developments |
| | | | The LEVITATE Policy Support Tool (PST) is publicly available as developed within EU Horizons 2020 research project LEVITATE with the active contribution of NTUA. The LEVITATE PST is the go-to, one-stop-shop to support decisions on Cooperative, Connected and Automated Mobility (CCAM) related interventions.
It is designed as an open access, web-based system that provides
interested users with access to LEVITATE methodologies and results. It
contains Forecasting, Backcasting and CBA estimator capabilities as well
as a rich Knowledge module serving as background and scientific
repository supporting the ensemble of quantitative and qualitative
estimates produced from the PST.   The NTUA presentation was titled LEVITATE – Policy Support Tool | | | |
| | | | The International Transport Forum (ITF) has published a new Report titled Monitoring Progress in Urban Road Safety: 2022 Update. This Report tracks the progress in reducing the number of road traffic fatalities and serious injuries in cities between 2010 and 2020. It is a unique combination of traffic safety data collected in 32 cities participating in the ITF Safer City Streets network and compares trends in urban and national road safety. | | | |
| | | | The World Road Association – PIARC implemented
an ambitious PIARC Knowledge Exchange project, aiming at sharing
knowledge about road safety, with the active contribution of NTUA,
especially within Low and Middle Income Countries with limited
resources but also in more developed economies with different needs and
priorities. The theme of this month refers to Vulnerable Road Users (VRUs), as presented by the PIARC Technical Committee 3.1 member Lawrence Chauke.
Throughout the year, PIARC will focus on the Safe System approach,
addressing safe roads and roadsides, safe road users, safe vehicles and
safe speeds. | | | |

| | | | NTUA Professor George Yannis has contributed actively at the ITF 2023 Summit held
in Leipzig, Germany, on 24-26 May 2023, on key discussions on the
design of safe and equitable future transport systems for all. In his presentation on Social Cost-Benefit Analysis of Key Urban Mobility Policies in Athens demonstrated
the high usefulness of the social Cost-Benefit Analysis (CBA) for the
promotion of key urban mobility and safety policies, including
comprehensive appraisal of externalities (impact on safety, environment,
congestion, etc.). The policies investigated concerned City-wide Speed
Limit 30km/h, Congestion Charging Schemes, Ridesharing Services and
Telematics Insurance Schemes, which were proved highly beneficial for
the society welfare. | | | |
| | | | NTUA Professor George Yannis has contributed actively at the "Vision Zero for the Balkans" Road Safety Conference organized by IRF in Belgrade, Serbia, on 15 May 2023, with the presentation titled "Network Wide Road Safety Assessments to diagnose road safety risk".
Some of the key issues of this conference are to promote the uptake of
“Vision Zero” policies and make a compelling case for safety
investment, focus on risk factors and road deficiencies that lead to
injuries among vulnerable road users and advance regional cooperation. | | | |
| |
| | | | A paper titled “A Review of Surrogate Safety Measures Uses in Historical Crash Investigations” authored by Dimitrios Nikolaou, Apostolos Ziakopoulos and George Yannis, has been published in Sustainability.
On that purpose, 34 studies were examined, providing insights on the
different types of SSMs collected under real road environment
conditions, the way they are collected, their connection with specific
road crash types, and the type of the developed statistical models are
examined and discussed. Particular focus is also placed on the temporal
dimension of the collection period of both SSMs and road crashes. Based
on the classification performance metrics of the developed models, it
was found that the Random Forests classifier outperformed the other developed classifiers in terms of predicting crash risk levels of the considered motorway segments.  | | | |
| | | | An NTUA Diploma Thesis called “Analysis
of the acceptance and cost benefit analysis of reducing the speed limit
to 80 km/h on the interurban road network in Greece” was recently
presented by Konstantinos Makrydakis. For the purpose of this Diploma
Thesis, a special questionnaire was developed and answered by 408
travellers, from different parts of Greece, based on the stated
preference method for 10 hypothetical scenarios with variations of the
variables travel time, fuel consumption and probability of road accident
with serious injury. The analysis calculated the investment costs and
the impacts on traffic, road safety and the environment expressed in
monetary units and showed that the reduction of the speed limit to 80
km/h on the interurban road network in Greece is considered to be economically very positive for the society, with a positive economic Net Present Value (ENPV=€170.7 million) and a high ERR (ERR=39.1%). | | | |
| | | | The PHOEBE research project has recently released the PHOEBE 1st Newsletter,
which provides information on the latest outcomes of the EU-funded
‘Predictive Approaches for Safer Urban Environment’ (PHOEBE) project
aiming to increase the road safety of vulnerable road users,
especially those who use active mobility and e-scooters. Special focus
is given to the assessment of current transport pilot plans in Athens,
carried out by NTUA. | | | |
| | | | The Horizon 2020 project i-DREAMS (smart Driver Environment Assessment and Monitoring System) released its 7th Newsletter,
presenting the main accomplishments of the project, through creative
solutions and risk mitigation strategies, exploiting state-of-the art
findings on driver safety tolerance zone. The Newsletter presents
the main results and the key findings from field trials and simulator experiments in Belgium, Germany, UK, Greece and Portugal and
recommendations are also provided. The management approach, the
communication and dissemination strategy as well as the ethical
challenges tackled are presented through 37 deliverables, technical
reports, interviews. | | | |
